Subject: [net-next 09/15] net/mlx5e: Add error flow when failing update_rx
From: Guy Truzman <gtruzman@...dia.com>
Up until now, return value of update_rx was ignored. Therefore, flow
continues even if it fails. Add error flow in case of update_rx fails in
mlx5e_open_locked, mlx5i_open and mlx5i_pkey_open.
